4age hitting gas too quick means engine stalls - what is the issue?

[Ryo]

My apology i released too much of my feelings. I am glad that you are helping me guy's. Yes you are absolutely right jondee86 i will be more precise with my investigation from now on to find the issue.
To answer your questions:
- No i was not driving the car i was taking it from my friend with non drivable condition.
- Fuel filter changed for a new one (Filtron brand) for exact type for AE92
- I was not able to check the fuel pressure as i have not measuring tool for that. I checked for prices on those and they cost too much to buy. Is there some workaround possible or should i try to borrow some (perhaps someone will have some but not quite sure).
- There was no rust in the fuel rail (in fuel) as i remeber when i was replacing the rubber seals on the injectors. Can be that i exchanged on some position but they look all the same.
First time when i started the engine i remeber that some pipe was leaking near the fuel tank but i managed to seal the leak. Of course i can't tell if the fuel pump from AE86 i installed is giving enough pressure as it is a bit old (but was working in my AE86 properly after i put it out and in box on shelf... was sitting there for longer time). I would like to properly investigate the issue from now on but i would like to create some plan how to proceed step by step to troubleshoot this.
